Safety Lesson One
Bellringer How do you know if you are hurt? Discuss the signs of an injury with a partner.
Objectives • Identifysix warning signs of injury. • Explainwhy you should let an injury heal completely. • Describeeight ways to protect yourself from injury while exercising.
Warning Signs of Injury • Pay Attention to the SignsSix warning signs of injury are: • 1. joint pain • 2. tenderness in a single area • 3. swelling • 4. reduced range of motion around a joint • 5. muscle weakness • 6. numbness or tingling.
Recovery from Injury • RICERICE is the treatment for most injuries. It is also useful while you heal. RICE stands for: • 1. rest • 2. ice • 3. compression • 4. elevation
Warm-Up and Cool-Down • Warming UpA warm-up gets you ready for exercise. It increases blood flow and loosens muscles and tendons. • Cooling Down A cool-down helps your body return to normal after exercise. It helps the heart return to its resting rate.
Stretch • How to Properly StretchTo avoid injury, stretch after a warm-up or cool-down. Stretch slowly, without bouncing. Stretches should be held about 10 to 30 seconds.
Don’t Go Too Fast • Know Your LimitsWorking too hard often leads to acute injuries, such as strains and sprains. Long workouts are also risky. The body gets too tired. You can lose concentration and get hurt.
Improve Your Form • Poor FormPoor form may put a lot of pressure on your muscles, joints, and bones. Using poor form over a long period of time can cause chronic injuries, such as tendonitis. • Learning the Correct Form You should talk to your teacher or coach before trying a new exercise. He or she can show you the correct form and help you learn it.
Take a Break • Let Yourself RecoverRest and recovery are important parts of a fitness program. Rest gives the body time to repair itself. Rest should be planned along with exercise in your fitness program.
Wear the Right Clothes • Special ClothingMany sports have special clothing needs. For example, football and hockey jerseys need to be large enough to go over safety equipment. • Consider the Weather Always consider the weather when you are dressing for physical activity. Dress in layers if the weather may change.
Shoes are very important and are often specialized to each activity.
Use Your Safety Equipment • Let Yourself RecoverSafety equipment serves two purposes: • 1. Safety equipment lets you try activities that would otherwise be unsafe. • 2. Safety equipment protects you in activities that are generally safe but in which accidents could happen.
Don’t Exercise Alone • Why Exercise with a Partner?If you get hurt while exercising alone, there probably won’t be anybody around who can help you. If you have friends around, they can help you or go get help.

What Is a Drug? • Changing Body or MindA drug is any chemical substance that causes a change in a person’s physical or psychological state. • Drugs vs. Food Unlike food, drugs do not give your body nourishment. You should take drugs only to treat an illness or a disorder.
How Drugs Enter Your Body • Almost all drugs that you take into your body end up in your bloodstream. However, drugs can be taken and can enter the bloodstream in several different ways, as shown on the next slide.
Drug Addiction • What Is Drug Addiction?Drug addiction is the uncontrollable use of a drug. • Drug Abuse The path to addiction usually starts with drug abuse. Drug abuse is the misuse of a drug on purpose or the use of any illegal drug. • Dependence: Dependence on a drug means needing the drug in order to function properly.
Physical Dependence • What Is Physical Dependence?Physical dependence is the body’s chemical need for a drug. An addicted person may experience withdrawal when he or she stops taking a drug. • What Is Withdrawal? Withdrawal is the process that occurs when an addicted person stops taking a drug.
Psychological Dependence • What Is Psychological Dependence?Psychological dependence is a person’s emotional or mental need for a drug. • Withdrawal Symptoms A person who is psychologically dependent on a drug may experience some withdrawal symptoms when he or she stops using the drug. These symptoms can include depression, nervousness, sleeplessness, and irritability.

Cocaine and Crack Cocaine • What Is Cocaine?Cocaine is a powerful stimulant that is produced from the coca plant, a plant that is native to South America. • Effects of Cocaine and Crack Cocaine Cocaine and crack cocaine cause intense feelings of euphoria. These feelings are very brief. They are followed by physical illness and a sense of depression.
Methamphetamine • Synthetic DrugMethamphetamine is synthetic, which means that it is produced in a laboratory. • Effects of Methamphetamine Repeated use of methamphetamine can cause severe damage to the body, including permanent kidney or liver damage.
Depressants • What Is a Depressant?Any drug that decreases activity in the body is called a depressant. • Effects of Depressants Depressants can be very addictive, and an overdose can cause coma, brain damage, or death.
Depressants, also called sedatives, can have a range of effects, from mild relaxation to deep sleep.

The Long-Term Effects of Marijuana • Mental EffectsMarijuana often decreases a person’s ability to think and concentrate. Marijuana also decreases energy and the desire to perform tasks or pursue goals. • Physical Effects Smoking marijuana can cause lung cancer and circulatory problems.
What Are Opiates? • Any drug that is produced from the milk of the opium poppy is called an opiate.
Opiates Are Addictive • Opiates can cause addiction very quickly, sometimes with just one use. • People who are addicted to opiates experience many withdrawal symptoms. These symptoms can include cramps, vomiting, muscle pain, shaking, chills, and panic attacks.
Heroin • Heroin is a drug that is made from morphine. • The effects of heroin include euphoria, sleepiness, a warm feeling in the skin, shallow breathing, and nausea. • A person can become addicted to heroin after just one or two uses of the drug.
Hallucinogens • What Is a Hallucinogen?A hallucinogen is any drug that causes a person to hallucinate. To hallucinate is to see or hear things that are not actually present. • A “Trip” The effects of a dose of a hallucinogen are often referred to as a “trip.” The length of a trip depends on the type and amount of the drug that is taken and can last from minutes to days.
Flashback • What Is a Flashback?Flashbacks are one of the many dangers of using hallucinogens. A flashback is an event in which a hallucinogen’s effects happen again long after the drug was originally taken. • Why Do Flashbacks Happen? Flashbacks happen because molecules of a hallucinogen are sometimes stored by the body in fat cells. When these cells are burned, the drug enters the bloodstream again.
Inhalants • An inhalantis any drug that is inhaled and absorbed into the bloodstream through the lungs. • Common inhalants include household cleaners, spray paint, and some glues. • Effects of inhalants include hallucination, lack of coordination, distortion of time and distance, and difficulty thinking or speaking. • Use of inhalants always causes brain damage. Even one use can cause immediate death.
Ecstasy • What Is Ecstasy?Ecstasy is the common name given to the chemical MDMA.

GHB • What Is GHB?GHB is a drug that is made from the anesthetic GBL, a common ingredient in pesticides. • Effects of GHB The effects of GHB include increased energy, euphoria, muscle relaxation, and increased sensitivity to touch. Other effects include dizziness, vomiting, loss of memory, trouble breathing, and an inability to move.
GHB • DangersMany people who use GHB lose consciousness. Many of them die. Death is even more likely when GHB is combined with other drugs, especially alcohol.
Ketamine • What Is Ketamine?Ketamine is a powerful drug that is closely related to the hallucinogen PCP (angel dust). • Effects of GHB Users of Ketamine experience a sense of dissociation, which means “separation from reality.” Other effects include hallucination, numbness, an inability to move, and loss of memory.
Ketamine • DangersMany users hurt themselves while using Ketamine because they are unable to feel pain. In other cases, Ketamine has been known to cause permanent memory loss and coma.
